Abstract
The invention relates to a powder conveying device. The device is composed of a powder storage system A, a powder pressing and conveying system B, a powder flow monitoring and adjusting system C, a powder weighing system D and a powder recycling system E; the power firstly enters the powder storage system A, and then enters the powder pressing and conveying system B under the effect of gravity and negative pressure of a pressurizer; after the powder flow monitoring and adjusting system C performs flow control, the powder is discharged in a continuous manner; when a constant-flow state is established or a verification coefficient of a measurement instrument is obtained before driving, the pressurized powder discharged from the powder flow monitoring and adjusting system C enters the powderweighing system D through valve switch, and the powder weighing system D weighs and computes the verification coefficient of the powder flow measurement instrument; and then the powder is depressurized by the powder recycling system E and returns to the powder storage system to be recycled. The device has a simple structure and a large flow adjusting range, requires small investment, is continuous and stable in operation, saves energy and is environmentally-friendly. Therefore, the powder conveying device provided by the invention has strong adaptability and a remarkably wide application prospect.
Description
【Technical field】 [0001] The invention belongs to the technical field of powder conveying. More specifically, the present invention relates to a powder conveying device. 【Background technique】 [0002] The high-concentration dense phase conveying technology is a solid particle (powder) conveying technology proposed relative to the low-concentration dilute phase conveying technology. As we all know, the high-concentration dense-phase conveying technology of powder generally has the characteristics of low energy consumption, large conveying capacity, wide conveying range, small abrasion of pipelines and materials, saving carrier gas consumption and gas power source, and saving pipeline material consumption. At the same time, the high-concentration dense-phase conveying technology is also conducive to reducing the generation of static electricity in pipeline transportation and improving the safety of conveying flammable and explosive materials. For occasions with heat demand,...
